Abstract

A 54-year-old man with multiple endocrine neoplasia type 1 had previous history of parathyroid surgery and left thyroid lobectomy 5 years earlier, and was referred for recurrent hypoglycemic episodes. Ga-DOTATATE PET/CT had showed multiple lesions in the right lung, liver, and pancreas. Biopsy from pancreas revealed low-grade neuroendocrine neoplasia. After 2 fractions of Lu-DOTATATE therapy, the size of lesions and its activity reduced on the Ga-DOTATATE scan and the hypoglycemic episodes manifested every day have scaled down to 1 time over 1-year follow-up. Herein, we report a case of malignant insulinoma successfully treated with radiolabeled somatostatin receptor therapy using Lu-DOTATATE.
